What is 1-Butanol?
Butan-1-ol is a primary alcohol that is butane in which a hydrogen of one of the methyl groups is substituted by a hydroxy group. It it produced in small amounts in humans by the gut microbes. It has a role as a protic solvent, a mouse metabolite and a human metabolite. It is a primary alcohol, a short-chain primary fatty alcohol and an alkyl alcohol.
